Device and apparatus for horticultural lighting and ventilation
View Patent ↗A device and apparatus to provide lighting and ventilation for horticultural applications. The invention relates to a device that combines lighting and ventilation into a single device that enables more efficient lighting and ventilation, and thereby greater control of the microclimate for high density indoor horticulture and controlled environment agriculture. The invention further relates to an apparatus comprised of an array of the devices and the networked control thereof.
1. A device for illuminating plants and circulating air, comprising:
a hollow body,
wherein the hollow body comprises at least one opening,
wherein the opening(s) is/are connected to at least one source of forced air,
wherein a surface of the hollow body comprises a plurality of holes,
wherein at least some of the forced air supplied to the hollow body through the opening(s) exits the hollow body through one or more of the holes,
wherein a plurality of light emitting diodes (herein “LEDs”) are attached to an outside surface of the hollow body,
wherein the LEDs are attached in a density sufficient to supply photosynthetically active radiation of at least 200 μmol/m 2 /s is at a distance of 1 inch from a surface of the hollow body,
and wherein at least a portion of the holes are on the same surface of the hollow body as the LEDs such that at least a portion of the forced air that exits the hollow body through said portion of the holes does so substantially parallel to the direction of the photosynthetically active radiation supplied by the LEDs.
2. The device of claim 1 , wherein the source(s) of forced air are selection from the group consisting of a fan and a central air handling unit.
3. The device of claim 1 , wherein the LEDs are attached in a density sufficient to supply photosynthetically active radiation of at least 200 μmol/m 2 /s at a distance of 1$ inches from the surface of the hollow body.
4. The device of claim 1 , wherein the LEDs are attached in a density sufficient to supply photosynthetically active radiation of at least 200 μmol/m 2 /s at a distance of 24 inches from the surface of the hollow body.
5. The device of claim 1 , wherein the LEDs are attached in a density sufficient to supply photosynthetically active radiation of at least 200 μmol/m 2 /s at a distance of 48 inches from the surface of the hollow body.
6. The device of claim 1 , wherein the LEDs are attached in a density sufficient to supply photosynthetically active radiation in a density of at least 200 μmol/m 2 /s at a distance of 96 inches from the surface of the hollow body.
7. The device of claim 1 , wherein the LEDs are dimmable.
8. The device of claim 1 , wherein the LEDs are connected to a timer controlling the on or off state of the LEDs.
9. The device according to claim 7 , wherein the LEDs are connected to a network capable of controlling the dimming remotely.
10. The device according to claim 8 , wherein the LEDs are connected to a network capable of controlling the on or off state remotely.
11. The device according to claim 1 , wherein the forced air supplied to the opening of the hollow body is sufficient to supply at least 1 cubic feet per minute of air though the cross-sectional area of one or more of the holes.
12. The device according to claim 1 , wherein the forced air supplied to the opening of the hollow body is sufficient to supply at least 10 cubic feet per minute of air though the cross-sectional area of one or more of the holes.
13. The device according to claim 1 , wherein the forced air supplied to the opening of the hollow body is sufficient to supply at least 50 cubic feet per minute of air though the cross-sectional area of one or more of the holes.
14. The device according to claim 3 , wherein the individual LEDs each have a power output of less than 0.5 watts.
15. The device according to claim 3 , wherein the individual LEDs each have a power output of less than 1 watt.
16. The device according to claim 3 , wherein the individual LEDs each have a power output of less than 5 watts.
17. An apparatus comprising an array of two or more of the devices according to claim 1 .
